쑥 분말 사료를 암돼지 및 거세돈에 첨가하여 그 수준에 따라 0%(T1, 암돼지, T2; 거세돈)와 1.5%(T3; 암돼지, T4, 거세돈)로 각 구별 45두씩 배치, 42일간 급여하여 생산된 돈육의 육질특성은 다음과 같다. 도체중량과 등지방두께는 73가 가장 낮았으며, 도체등급에서는 처리구간 유의차가 없었다(P>0.05). 쑥 분말 급여시 암돼지간(T1과 T3)에서는 조회분, 거세돈간(T2와 T4)에는 조지방 및 조회분 함량이 유의적으로 증가하였다(P<0.05). pH는 저장기간에 증가함에 따라 모든 처리구에서 감소하였으며, 쑥 분말 급여 처리구(T3와 T4)에서다소 높은 pH값을 나타내었다 드립감량은 처리구간에 일정한㎏/㎠경향을 나타내지 않았지만 저장기간이 경과함에 따라 높아졌다. 전단가(shear force, ㎏/㎠)는 T1을 제외한 모든 처리구에서 저장기간이 길어짐에 따라 감소하였다. 명도와 적색도는T3가 T1 보다 다소 높은 수치를 보였으나, 거세돈간(T2와 T4)에서는 오히려 낫게 나타났다. 저장기간이 증가함에 따라 TBARS와 VBN값은 공히 유의적으로 증가하였으며(P<0.05),쑥 분말 급여 처리구(T3 및 T4)에서 유의적으로 더 높게 나타났다(P<0.05). 지방산 분석결과, 포화지방산(saturated fatty acids)은 대조구에 비해 쑥 분말 첨가수준 증가에 따라 포화지방산은 높아지고 상대적으로 불포화지방산(unsaturated fatty acids)은 낮아지는 경향이 있었으나 유의차는 없고, 콜레스테롤의 경우에도 동일하게 유의적인 차이가 없었다. 전체적인 기호도는 신선육 및 조리육 공히 처리구가 낮은 점수를 얻었다. 향후 쑥 분말 급여에 대한 보다 많은 연구가 진행되어야 할 것으로 판단된다. This study was carried out to investigate the feeding effects of mugwort powder on meat quality characteristics for 42 days. The results obtained were as follows; Carcass weight(㎏) and backfat thickness(㎜) of T3 showed the lowest compared with other treatments. Grade scores were not significantly differ among the all treatments. In the proximate composition, crude ash content was higher(P<0.05) in the T3 than that of T1, while, crude fat and crude ash contents in T4 were higher(P<0.05) than those of T2. pH values were tended to low as storage period extended, in particular, those values slightly higher in the T3 and T4. Drip loss(%) was tended to increase during storage. Shear force(㎏/㎠) in all samples showed the decreased during the storage, except for Ti. L^(*) and a^(*) of T3 were slightly higher than those of T1, while, T4 was lower than T3. TBARS and VBN of all samples were significantly increased(P<0.05) as storage period extended, those values significantly higher(P<0.05) in the T3 and T4. There were no differences in saturated fatty acids, unsaturated fatty acids and cholesterol of pork meat between control(T1 and T2) and treatments(T3 and T4). The sensory score of pork samples fed with mugwort power were lower than that of control(T1 and T2) in both fresh and cooked meat. Further studied are needs on the pigs fed with mugwort powder.

核分裂 및 放射化生成物質에서 放出하는 여러가지 감마선들은 核燃料를 破壞하지 않고도 推出할 수 있는 많은 情報를 包含한다. 그러나 半導體 檢出器에서 얻은 복잡한 스펙트럼에서 이러한 정보를 推出하기가 容易하지 않기 때문에 電算코드의 使用이 必要하게 된다. 本 硏究에서는 그동안 國際的으로 널리 普及되어 使用되는 감마선 分析 프로그램들의 長點을 취하여, 감마선은 물론 X-線의 스펙트럼도 피팅(fitting)하여 피이크의 중심과 면적을 正確히 計算할 수 있는 전산코드 CAERI를 開發하였다. CAERI는 FORTRAN으로 쓰여있고, 특히 固有輻射線幅(natural line width)을 무시할 수 없는 X-線의 피이크 表現函數인 Voigt 函數에 대해서는 다른 X-線 分析 프로그램들이 使用한 간단한 近似式 대신에, 더욱 正確한 無限級數近似式을 사용하였다. 특히 CAERI는 U이나 Pu과 같은 重元素의 核種分析時에 直面하는 감마선과 U이나 Pu의 X-線이 任意로 ()()하여 共存하는 복잡한 스펙트럼까지도 取扱할 수 있다. ()Lu감마선과 ()U K()X-線의 試驗스펙트럼을 피팅하여 다른 프로그램들의 피팅결과와 비교했을 때 좋은 一致를 보았다. A great variety of nuclear gamma rays emitted from fission and activation products of spent nuclear fuel contains much information that can be clicited without affecting the integrity of the fuel elements. But the extraction of such information form the comples spectrum is difficult and requires computer codes. In the present work, a versatile code "CAERI" was developed which located peaks and calculates their areas for X-rays as well as gamma rays using elegant features of some widely used program for gamma-ray peak fitting. "CAERI"coded in FORTRAN used infinite series approximation more accurate than other workers various simple, piecewise series approsimations for evaluations of the Viogt function which represents the X-ray peak with non-negligible natural line width. "CAERI" can handle even a complex multiplet consisting of peaks from X-rays and gamma rays in arbitray mixture, which one often encounters in the isotopic analysis of heavy elements such as U and Pu. The results of the fitting performed on the test spectra of ()Lu ()-ray and ()U K() X-ray show good agreement with those by previous workers.

Objective : This study is performed for the purpose of examining the efficacy of the scolopendrid(Scolopendra morsitans L) which has been to low back pain as a folk remedy. Methods & Results : Seventy patints with H.I.V.D. treated with the scolopendrid aquacupuncture and examined 4 tests; D.I.T.I., physical test, Oswestry disability index, and self-conscious pain rate were studied. And we follow up after discharge, we evaluated the present state and recovery period. Or we evaluated by herniated type and duration of onset. There was 58~97% of efficacy rate in each tests. Moreover, statistically valuable change in all 7D.I.T.I. points and in disability index and in self-conscious pain rate was showed. Conclusion : The scolopendrid aquacupuncture is possible to be effective terating the H.I.V.D patients. so we suggest the possibility using this new remedy to the H.I.V.D. patients.

한영근,김성훈,이동녘,구범회,김연범 明知大學校 産業技術硏究所 2008 産業技術硏究所論文集 Vol.27 No.-

There are many potential dangers around our life, but we are laking in the consciousness of safety because accidents do no happen frequently. If an accidents occurs, an ability to deal with it is so weak that it can be enlarges to a disaster. Therefore it is important to accustom ourselves to manage dangers and this can be realized by traing. In this study, the traditional traing methodologies are compared and analyszed in order to find an efficient traing way for the public. Also, we propose a traing method by using UCC(User Created Contest) which is a growing communication and content tool in the Internet environment nowadays.

The purpose of this study is to examine the rating of perceived exertion at lactate threshold for exercise prescription. The number of experimental subjects were forteen. The endurance training intensity corresponding to lactate threshold(LT) was administered 30 minutes a day, 3 days a week, for 8 weeks. The results of study were as follow ; 1. The mean VO₂max of control subjects were 3.42 l/min and 3.36 l/min before and after training. And that of experimental subjects were 2.69 l/min and 3.80 l/min before and after training. 2. The mean VO₂max at lactate threshold in control subjects were 2.21 l/min and 2.03 l/min before and after training. And that of experimental subjects were 2.20 l/min and 2.79 l/min. 3. The mean RPE-LT corresponded to a perception of work as "fair light" and "Hard." 4. The endurance training decreased RPE scale significantly during the maximal exercise.

비육후기 돼지 사료에 첨가되는 우지 함량 중 2%를 들깨유로 대체 급여한 돈육(T1), T1처리구에 비타민 E 250ppm 첨가 급여한 돈육(T2), 우지함량 중 2%를 오징어유로 대체 급여한 돈육(T3), T3에 비타민 E 250ppm 첨가 급여한 돈육(T4)을 1±1℃에서 28일간 저장하면서 육질특성을 조사한 결과는 다음과 같다. 저장기간에 따라 육색 L^*과 b^*값, 지방색 b^*값 및 drip loss는 증가하였다. 총단백질추출성과 보수력은 14일까지 증가 후 감소하였으며, 염용성 단백질추출성 및 지방색 L^*값은 감소하였다. 근절길이에서는 저장기간에 따라 T3구는 감소하였다. 총단백질추출성은 T1보다는 T2가 낮은 반면 T3보다는 T4가 높았다. 염용성단백질추출성은 비타민 E 첨가구들이(T2, T4) 첨가하지 않은 구들(T1, T3)에 비하여 높았으며, drip loss와 육색 a^*값은 비타민 첨가구들이 첨가하지 않은 구들에 비해 낮게 나타났다. 보수력은 T1보다는 T2가 낮은 반면 T3보다는 T4가 높았다. 지방색 L^*값은 저장 1일째는 비타민을 첨가한 처리구들이 첨가하지 않은 처리구들에 비해 높았으나, 저장 28일째에는 낮게 나타났고, b^*값은 비타민을 첨가한 처리구들이 낮게 나타나 비타민 첨가구가 drip loss, 육색과 염용성단백질 추출성에서 좋은 효과를 나타내었다. The quality of pork meat was determined as following treatments. The meat samples were obtained from pigs which had been fed finishing pig diets containing 2% perillar seed oil in beef tallow(T1), 250ppm vitamin E in T1(T2), 2% squid oil substituted of beef tallow(T3), 250ppm vitamin E in T3(T4). During storage period, meat color L^*, b^* value, fat color b^* value and drip loss were increased. The extraction amount of total protein and water holding capacity were increased until 14 days after then were decrease. The extraction amount of salt soluble protein and fat color L^* value were decreased and sarcomere length were decrease in T2 as well. T1 was higher than T2 in the extraction amount of total protein and its of T4 was higher than T3. The extraction amount of salt soluble protein of the T2 and T4 was higher than that of T1 and T3. The drip loss and the a^* value of meat color were lower in vitamin treated one than non treated one. On water holding capacity. T1 was higher than T2 and T3 was lower than T4. The L^* value of fat in vitamin treated ones was shown higher than that of non treated ones on day 1, however, it and the b^* value of the meat were low on day 28.
